How do you replace expansion valve on a Subaru 1998 Outback?

To replace the expansion valve on a 1998 Subaru Outback, first, ensure the A/C system is fully discharged by a professional to avoid refrigerant exposure. Remove the dashboard or center console components as necessary to access the A/C evaporator. Disconnect the refrigerant lines from the expansion valve, unbolt the valve from its housing, and replace it with the new one. Finally, reassemble all components and recharge the A/C system.
